GATE.

SPECIFICATION forming part of Letters Patent No. 260,440, dated July 4, 1882. Application filed February 24, 1882. (No model.)

To all whom it may concern:

Be it known that YI, EDWARD G. Woon, a citizen of the United States, residing at Kokomo, in the countyof Howard and State of Indiana, have invented a new and usefulGate, of which the following is a specification.

My invention relates to improvements in that class of gates known as automatic gates 5 and the objects ot' my improvements are to construct a cheap, simple, and durable automatic gate, which will be perfect and sure in its operation, easy to operate, and one that will not be liable to get ont of order. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view ot' my gate.

Figs. 2 and 3 are top views of' the upper hinge' mechanism. Fig. 4 is a longitudinal view of the gate-connections. Figs. 5, 6, and 7"are views of the upper hinge mechanism. Fig. 8 is a vertical section of the upper hinge mechanism, and Fig. 9 is a separate "iew of the bolt c. i j Similar letters refer to similar parts throughout the several views.

The gate-frame y may be made ot' various styles and sizes, and being provided at one end with an ordinary latch, p, and at the other end with a pintle, i, and a part of the hinge lc', it is ready to be suspended to the post. The bracket o is then irmlysecured to the upper end of the posts. This bracket is provided with slots c and o', latchesc c', and plates u, as shown in Fig. 6, and for the purpose hereinafter specified. The bolt eis made larger in the center, or provided with a nut or square collar, e, made fast to it, as shown in Fig. 9, and has a nut on each end. It is secured to the Vbracket o by placing it in the slot c and tightening the nut on the under side. The under plate, b, and top plate, a, may-be then placed on the bracket, (the upper end of the bolt e passing through the holes e and b' in both plates.) The latches c (being provided at one end with a coil-spring) are then secured to the sides of the bracket between the plates u. A bolt, u', passing through the slots in the outward ends of the plates, secures the latches in position. One end of the'latch'works in the slot o and the other end, c', extending outward, so that it will engage in one ot the notches 4, 5, 6, 7, or 8 in the plate b, as shown in Figs. 2 and 3, and by dotted pla-te in Fig. 6. The gatet`rame y may be then placed on the lower hinge, k, and the pintle't made to engage in the hole b, and slot t" in the plates a and I). A nut is then placed onthe upper end of the bolt e and tightened sufficient to allow the plates to turn easily. The under nut on the boite is then loosened and adjusted so as tomake the gate swing and latch properly, and then tightened. After this is done the cords or wires m are then attached to the ends ot' the rim a on the top ol' plate a, as shown in Figs. 2 and 3. The other ends ot' these cords m are attached to the slides f on each side of the gate. The slides f consists of a piece of metallic rod or bar bent in a peculiar shape most clearly shown in Fig. 1, being made larger and heavier at its lower end, above which is an opening,f, leadinginto openingf' by the narrow space between them. The openings are made large enough to allow the end of the crank d to turn in them, the space f' taper ing upward to a point just above the crank d, as shown in Fig. l. 4'lhe said slides Work on the cranks d", which are attached to the posts h. These posts are placeilon each side and a proper distance from the gate, so that it may strike and latch to them each time it is opened.

The trip-rods g are placed a few feet from the posts h, as shown in Fig. 4, and connected to the crank d by a small rod, g. This crank is hinged a proper distance from the ground, so that the weight n on the arm d will swing free. When the gate is closed everything stands as shown in Figs. l and 2, and when a vehicle-wheel presses the trip-rod down the two cranks d d are turned downward and the slidef and arm d are thrown into a horizontal position, as shown by the dotted lines in Fig..4. .When the slide fis thrown into a horizontal position it'pulls the cord m. This causes the plates a and b to turn, as shown in Fig. 3. When the cord is pulled it first turns the top plate, a, (not moving the lower one,) the length of the slot t. In so turning one of the incline notches, 1 or 3,wi1l press the end ot' the latch c out of the notch 5 or 8, and both plates then revolve, as shown in Fig. 3. When I ce the cord is pulled from one side of the gate the slidefon the other side is drawn up toward the top of the post h, so that the enlarged plaeef is drawn up around the flat end ofthe crank d, and when the front Wheel of a vehicle passes over the crank g" (it' thc vehicle is moving toward the crank 9) it pulls the slidefdovvn some, but not sufficient to close the gate. When the front wheel is 0E of the trip-rod it rises and the flat end d slides up in the openingf. Then, whenthe rear wheel presses the trip-rod down, it pulls the cord sufcient to close the gate, and thus the gate operates, always opening in the direction the vehicle is moving.

Having thus described my invention, what I claim is- 1. In an automatic gate, the combination of the trip-rods with a swinging crank, d, which 2o is provided with a slide,f, having openingsf f, for the purpose set forth.

2. In a gate-hinge mechanism, the plate a,

having an elevation, a', slot i, and incline notches around its outer edge, plate b, having two holes in it and notches around its outer edge, bracket o, having slots v and o', and provided with the plates u for supporting the latch c, for the purpose set forth.

3. The combination ot' plate a, having slot and incline notches, plate b, having two holes in it and notches around its outer edge, bracket o, wire m, post s, and gate y, for the purpose set forth.

4. rlhe combination of the slidef, having openings ff, crank dal d", weight n, post h, wire g', and trip g, for the purpose set forth.

5. In an automatic gate, the trip-rod g, rod g', cranks d d, arm d, Weight n, slide f, and wire or cord m, in combination with the hinge mechanism, for the purpose set forth.
